# CALP.PRO

> Crypto Arbitrage Liquidity Provider — a platform for discovering and evaluating multi-hop arbitrage opportunities across decentralized exchanges.

CALP.PRO helps traders and developers identify profitable arbitrage paths between token pools on centralized and decentralized exchanges. The platform supports configuring exchange sources, scanning token/pool pairs, and calculating ROI across multi-leg arbitrage routes.

## Core Features

- **Exchange Configuration**: Connect and manage multiple exchange sources (CEX and DEX).
- **Token & Pool Discovery**: Browse and select token pairs and liquidity pools for analysis.
- **Arbitrage Path Evaluation**: Build multi-hop arbitrage routes (Init token → Next token → Next token) and compute expected ROI percentage for each path.
- **ROI Scoring**: Each arbitrage route is evaluated and ranked by return on investment.

## Use Cases

- DeFi arbitrage bot development and backtesting
- Liquidity analysis across AMM pools (Uniswap V2/V3, SushiSwap, etc.)
- Multi-leg token swap route optimization
- On-chain trading strategy research

## Target Audience

Quantitative traders, DeFi developers, and algorithmic trading teams looking to automate or analyze cross-exchange arbitrage on Ethereum and compatible chains.
